Hidden additives


Consumers want to avoid ADDITIVES, so food manufacturers have switched to adding innocent-sounding INGREDIENTS which contain these same additives, often claiming ‘no added whatever’.

Here is how you can recognise this trickery for the two most important additives that people seek to avoid – propionate bread preservatives and MSG.

See also hidden nitrates/nitrites.

The latest scam is to get the additives classified as Processing Aids. These do not appear anywhere on the label. See what is coming in future food products with hidden Processing Aids.

Propionate bread preservative 282


Of the 19 ways in which propionate preservatives can be added to food,
only 8 are regulated and must appear as additives. The rest are hidden and so in unregulated amounts.


CLAIM:
the package often says ‘no artificial/added preservatives/additives’

INGREDIENTS TO LOOK FOR:

  • ‘cultured’ OR ‘fermented' AND ‘wheat/wheatflour/flour/whey/dextrose/and several other things
  • OR EVEN ‘starter culture’ (in some bread products - don't forget that sourdough bread contains high levels of propionates)
  •         AND EVEN in organic products - read the label!

Monosodium glutamate MSG 621


Of the 131 ways in which glutamate flavour enhancers can be added to food,
only 12 are regulated and must appear as additives. The rest are hidden and so in unregulated amounts.


CLAIM:
the package often says ‘no added MSG’ - if the packaging says anywhere ‘no added MSG’ then it is very likely that there IS added MSG in another form.

INGREDIENTS TO LOOK FOR:

If the ingredients label includes any of 131 names in the following table (plus MSG), there MAY be free glutamates (which is the same as adding MSG).

There is CERTAINLY added MSG in one form or another if these appear: 627, 631, 635, ribonucleotides, nucleotides, disodium guanylate, disodium inosinate, disodium 5'-ribonucleotides.

More buck passing, more hidden additives in our food due to government inaction.

Nitrate/nitrite preservatives 249-252


Of the 14 ways in which nitrate/nitrite preservatives can be added to food,
only 8 are regulated and must appear as additives. The rest are hidden and so in unregulated amounts.


CLAIM:
if the label on ham or bacon says “No added nitrates/nitrites” then it almost certainly DOES contain added nitrates, usually in the form of a celery extract.

Watch out for “100% or all natural”, that is a warning to read the Ingredients Panel closely. Organic products can also contain this hidden additive.

INGREDIENTS TO LOOK FOR:

celery powder / vegetable extract / beetroot powder / fruit extract / grape extract

Processing Aids

The international Codex Committee on Food Additives have been asked by Japan to assess two enzymes which increase flavour enhancers inside foods without consumers ever knowing.

One will increase flavour enhancer 631 Disodium-5′-inosinate in foods but not appear on the label as they want it to be called a Processing Aid.

The second will convert the amino acid L-glutamine to flavour enhancer MSG L-glutamate to “in the manufacture of glutamic acid-rich yeast extracts...” This will also not appear on the label as they want to call it a Processing Aid.

It is clear that these enzymes are intended to perform a technological function. As consumers, we want to have these Processing Aids in daylight and on the label! more detail

The list above comprises all legally regulated sources of glutamate, and all known ways in which free glutamates are currently or might be added in Australia and New Zealand, including several (*) which are clearly intended to mislead (eg natural flavour) but are in use by the food industry. In some cases, the presence of MSG-boosters 627, 631 or 635 on the ingredients label were taken as evidence that some other ingredient (eg soy protein) was in a form upon which the boosters could act.

New Processing Aid applications

3’-Adenosine-5’-monophosphate deaminase from Aspergillus oryzae by Shin Nihon Chemical Co., Ltd. “AMP deaminase from Aspergillus oryzae is intended for use during food and beverage processing to increase the content of 5’-monophosphate (5’-IMP) in food, beverages or food ingredients to impart or enhance flavour”. See more on the “crystal meth of MSG” 

Glutaminase from Aspergillus niger by Shin Nihon Chemical Co., Ltd. “The enzyme catalyzes the conversion L-glutamine to L-glutamate, and is used in the manufacture of glutamic acid-rich yeast extracts and glutamic acid-rich protein hydrolysates. These, in turn, are added to other foods, including beverages, to impart savoury or umami taste”. See more on MSG and natural glutamates
